As an example: > Addr := "/192.168.1.1/192.168.2.1/10.1.2.3:80/" and Port := "81" would make > listening on port 81 for 192.168.1.1 and 192.168.2.1, and listening on port > 80 for interface 10.1.2.3. Now let's assume that application listens on two ip:port pairs, each for different kind of communication. For example, 192.168.1.1:2048 and 192.168.1.1:27015. Also, let's assume that user can define on which ip:port one of servers should listen (another ip:port pair would be fixed). What happens if user enters "/192.168.1.1:2048/192.168.1.1:27015/" (for example, because he/she heard/read somewhere that with new ICS this is possible, and the application is based on ICS)? There would be clear conflict between either: - one of server components that now owns both ports and another that attempts to bind to owned port *or* - the second component that correctly owns 27015 port and first component that attempts to bind "subservers" to both 2048 and 27015 ports (depends on component creation order). While that change doesn't directly break existing code, it might introduce difficult to understand bugs, as seen above. One workaround I see now is to filter the user input, but that adds new code to equation. Another, and what I think the most reasonable, is to create a new class derived from TWSocketServer that would accept such input and leave original TWSocketServer untouched. Just my 5€. -- Piotr Dałek enigmati...@interia.pl ---------------------------------------------- Chcesz wiÄcej zarabiaÄ?
